First just a comment... please reply mails like this back to the list, so 
anyone can read them.

You could send a package to the OLSR subnet and the OLSR nodes would "grab the 
package" and retransmit it to it's final destination, but unless you are in 
direct radio range of your target it would have no way to send an answer.

Because no OLSR node has a route with gateway (next hop) for your net you 
would only get the answer if you can answer the ARP request of the target
of your original package (direct communication range).

A bridge is no router, so there would still be not multihop traffic flow
between the two networks, unless you set a HNA entry and a route I think.
